The Hitachi HTS542516K9SA00 160GB is a 2.5" 160GB Hard Disk Drive.
It uses the SATA 1.5Gb/s interface and has a speed of 5400 RPM.
|Drive Type||Hard Disk Drive||This defines whether the drive is a large-capacity slower hard disk drive, a smaller-capacity but much faster solid-state drive, or a hybrid|
|Physical Size||2.5"||The size of the drive dictates which drive bays it will fit into - generally a small drive will fit into any bigger drive bay with an adapter|
|Capacity||160GB||The drive storage capacity is the limit to the size of files that can be stored|
|Release Date||01 Nov 2005||The later the release, the more likely manufacturer support will still be around|
|Cache Size||8MB||The bigger the cache, the more data that can be temporarily stored for faster access|
|Power Required||5W||HDDs should generally require very little power to run, and SSDs even less|
|RPM||5400 RPM||The higher the RPM, the faster the hard drive, and the faster stored data can be accessed|
|Drive Interface||SATA 1.5Gb/s||The interface is the type of motherboard connection and defines the bandwidth limit of the drive|
The Hitachi HTS542516K9SA00 160GB is a hard disk drive, which means it stores data using quickly rotating disks, or platters, that can be read and written on via the moving actuator arm. Hard disk drives generally have a large storage capacity, and so are perfect for large amounts of data. The potential performance is well below that of solid-state drives, but they can definitely still hold their own. The Hitachi HTS542516K9SA00 160GB is a bottom of the range hard disk drive, and should only ever be used as basic data storage.
With a cache of 8MB, the Hitachi HTS542516K9SA00 160GB can store a very small amount of data temporarily. Loading data that has previously been loaded will result in barely any difference in access speed and load duration. At a speed of 5400 RPM, the hard disk drive spins at a below average speed. This speed is common for laptop hard drives, and may have long-term reliability and low-power benefits, but the resulting hard drive performance is noticeably slow.
With a capacity of 160GB, the Hitachi HTS542516K9SA00 160GB has a tiny amount of storage space for an hard disk drive. Using the SATA 1.0 1.5Gb/s interface this hard disk drive will most likely not be limited by its connection with the motherboard so much as by its own low performance.
A form factor size of 2.5" is standard for laptop drives and solid-state drives, and this will fit into any 2.5" drive bay. These drive bays are not yet ubiquitous, but it will also fit into a standard 3.5" or 5.25" drive bay with the appropriate adapter.
